Question: what are the biggest fallacies of people that post on hackernews?
Answer: One of the biggest fallacies of people that post on Hacker News is the nirvana fallacy, which is when someone jumps from "thing x is imperfect" to "thing x is worthless" without considering any of the benefits. People also tend to be familiar with certain technologies and will discount the flaws of existing technology vs. the flaws of new technology. Another fallacy is the assumption that there is one best tool for doing things - the one that supports the largest amount of use cases. Additionally, people may use appeals to authority, invent their own solutions rather than use existing ones, and assume that the approaches they first learned are most correct. Finally, people may assume open source software is a gift and that dependencies don't need to be tested.
